How Many ICD-10 Diagnoses to Report on CMS 1500 Forms
Question: How many ICD-10 diagnosis codes can you report on the CMS 1500 form?
Answer: Your first thought may be 12, which is an increase from the old form’s limit of four.
Though you may indeed report a total of 12 diagnosis codes, you can only link four codes to each CPT code reported.
Example: What should you submit on the exam if the patient has a different type of glaucoma in each eye and blepharitis on all four lids? That equals six ICD-10 codes, but you can’t link six diagnosis codes to one service.
Solution: Submit the two types of glaucoma and at least one of the lids for blepharitis. The claim should still be processed correctly.
